TECHNICAL FIELD OF THE INVENTION

The present invention relates generally to hunting accessories and, moreparticularly, to devices for bow sighting devices for establishingaiming positions while using a bow.

BACKGROUND OF THE INVENTION

There are a large number and variety of bow sights available on themarket, all designed with the primary purpose of enabling a user to moreaccurately deliver an arrow to a target. Many of these do not considerthe use of the equipment as hunting equipment that can be used in bothday and night. And conventional hunting equipment mimics equipment usedfor personal combat; for example, sighting devices were developed toprevent the emission of light from the source so that the target cannotidentify the user in a combat situation. However, in a huntingsituation, the game does not generally hunt back, and there is no needto shield the game from light source emissions. Although hunting andarchery technologies have progressed over time, modern archery bow andarrow systems typically do not use any equipment that jeopardizes theillumination of the archer, or shooter. The modern day hunter may tracka target from daylight to the evening. At dusk, the hunter is left withonly limited resources to track the target. The conventionalconsiderations regarding illumination, pointing devices, and displaysmust be thrown out when developing hunting equipment for use in dusk ornight.

An arrow is typically shot using the arms to pull back the bow string,and to aim and sight by holding the bow and arrow next to the archer'seye. Typically, a bow sight comprises a plurality of pins that may beadjusted by the archer for aiming at targets at different distances.Some bow sights have a single adjustable pin that is moved to the matchthe distance to the target. Normal multi-pin sights simply have severalbrass aiming pins which stick out horizontally from a vertical framemounted in front of the hand grip on the bow. Each pin corresponds to aparticular target distance. The archer visually estimates theappropriate range and then sights to the target using the appropriateaiming pin corresponding to that range. A recent innovation involves theuse of light gathering fiber optic filaments which provide a selfpowered illuminated dot that the archer sees at the end of each aimingpin. These fiber optic multiple pin sights have greatly improved theutility of such sights in low light or low contrast lighting situations.

FIG. 1 shows a prior art archery equipment having an archer 100 with aconventional compound bow 110 and a bow sight 120. The bow sight 120contains pin settings adjusted for 20, 40, 60, 80, and 100 yards,respectively. There is an LCD display that is connected to a laser 130,typically a range measuring conventional laser. The sight may contain apin sight system wherein LED light is transmitted to the sighting pinsvia fiber optic cables. Such a system is described in U.S. Pat. No.6,073,352, titled “Laser bow sight apparatus,” invented by Dunne et al.In this figure, the pin sight system contains pins and the user willwant to calibrate the laser and adjust the pin settings to set aspre-set values using the laser calibration to measure distance beforefiring the arrow 140. In this prior art, the pin settings and theoptical fibers and LEDs are taught to be utilized with multi-pin sights.

Aiming devices are commonly referred to as “sights” and allow archersto, after sighting in the bow, align an end of a pin with an intendedarrow striking position on a target. For purposes of this application,“sights” will also include cameras or videos able to aim at a particulartarget. These sights are not limited to archers; they can apply tovariety of shooting equipment, such as rifles, pistols, and crossbows.(U.S. Pat. No. 5,491,546A) Pin-based sights typically include multiplesight pins that are vertically spaced from each other and positionedsuch that different pins are used for shots of different yardages.Accurate use of a multiple pin sight requires accurate range or targetestimation by the archer. Laser and other light beam sights for firearmsare well known, but they have been little used with bows because theirmounting arrangements and range adjustment capabilities are ill suitedto the needs of the bow user. U.S. Pat. No. 5,419,050 titled “Rangeadjustable laser sight for bows” is directed to an adjustable laser beamsight that comprises a sight adapted to mount to a wide variety ofmodern bows and which provides quick and easy adjustment for ranges andtrajectory drops of magnitudes characteristic of a bow and arrow. Atrajectory from a bow will drop much more than a bullet fired from mostfirearms. The '050 Patent compensates for large drops in the arrowtrajectory is needed in connection with a bow mounted laser sight.Accordingly, there is a continuing need for an improved light beam sightsuitable for use with bows.

There are set difficulties for a hunter that hunts from daylight todusk. For example, from a free-standing distance, the settings that areestablished for the laser sight and the pin settings may be lost withthe loss of daylight. This is compounded by the fact that the game doesnot stay still long enough for the archer to draw and release an arrowafter finding the range to the animal, whereby the shot opportunity islost due to the time required for shot preparation.

The use of night vision goggles to spot targets at dusk is well known inthe industry. The night vision goggles conventionally work with IRillumination devices. The problem with the use of night vision goggleswith hunting bow equipment is the need for the archer to remain steadyduring a shot.

As shown in FIG. 2, the prior art archer 200 uses a conventional bow 210with a pin setting system 240. In this figure, the pin settings arecalibrated at 20, 40, 60, 80, and 100 yards respectively with pinsettings 241, 242, 243, 244, and 245. These pin settings are calibratedduring the daylight when the archer 200 has plenty of light to makenecessary modifications to distances with known targets. While huntingat night, archery bow hunters are required to perform numerous actssimultaneously to ensure accuracy of a shot. An archer must hold the bowone-handed at a full arm extension while drawing the bowstring with theopposing arm to the full extension of the bowstring. The archer mustthen attempt to hold the bowstring at full extension while aligning thesighting device eyepiece 247 with the target animal. At night, thearcher may use night vision goggles 260 to see the target while takingaim. Unfortunately, the night vision goggles 260 interferes with thearcher 200 and the necessary steadiness that is needed to take a shot atan animal. Generally, components 261 of the night vision goggles caneven interfere with the rest of an archer's natural position on the bowstring 220. This is further complicated by the given the amount ofaccessories available for archery bows, which may weigh upwards of tento fifteen pounds and may be unequally weighted. Thus, any equipmentattached to the head or arm of the archer during the execution of thebow fire will potentially interfere with the aim. Night vision gogglesare often even bulky and heavy, which will further interfere with anarcher to remain steady. Thus, there is a need for use of sophisticatednight vision capabilities without the conventional night visionequipment. As shown in FIG. 2, the use of prior art night vision goggles260 is rather awkward when used with the sophisticated bow sight system210. As shown, archer 200 is pulling back on bow string 220 aiming hisarrow 230 in his bow 210. In this system, the archer's face is so closeto the bow string 202 that it is either touching the string or veryclose to touching the string. The archer uses a peep sight that islocated in the bow string (200). Thus the archer must look through thepeep sight and see the sight pins to aim the bow. Night vision googleswill preclude the archer from viewing through the peep sight making itimpossible to sight the bow using the current sight pins. The nightvision goggles 220 is awkwardly located that prevents the archer fromcomfortably getting close to the bow 210 and using the sight pin system204.

What is needed is a sight system used for a bow, or a rifle, pistol, orcrossbow, wherein the user can calibrate settings during one time periodor environment to be used in a completely different setting and timeperiod, or different environment. More specifically, what is needed is ssystem that allows a user to calibrate a visible laser system during theday to match certain targets with certain distances, and to allow theuse of those settings for a different night time laser. Morespecifically, the user may calibrate another sight, such as a video, sothat they all or separately calibrate together. To enable this, separatesights must be coordinated so that adjustments made in one sight istransferable to another. What is further needed is a system thatdisplays to the user to calibrate different pin settings with one sightsystem that allows those pin settings to be used with a different sight.What is needed is a sight that will allow the hunter to quickly gaugethe magnification and zoom of the lens to show an impact point of theprojectile. What is needed is a laser targeting system that can switchfrom visible to evening dusk light without the hunter needing torecalibrate. What is needed is an integrated camera system for instantand future playbacks. These components must all include the capabilityto include these features in a standard sight adapted for a bow. Inlight of the foregoing, a bow sight is desired that improves the stateof the art by overcoming the aforesaid problems of the prior art.

SUMMARY OF THE INVENTION

In accordance with one aspect of the invention, a bow sight system isprovided that allows an archer to calibrate his bow based on a number ofdifferent environmental conditions. The sight system includes aconventional, visible laser sight for use of the target laser spotduring visible hunting hours during the day. The sight system furtherincludes a wheel mount for quick connection and disconnection. The sightalso includes an infrared illuminated and IR laser that is coordinated,or calibrated, with the visible laser. The IR laser system includes anLCD screen that shows the intended crosshairs of the target. The IRlaser system and the visible laser system and the LCD screen are allcoordinated such that calibrating one matches the calibration on theother sighting system.

A hunter can use both the red, green or visible laser and the infraredlaser to compensate for situation-specific shooting and environmentalfactors that influence arrow flight and targeting. And the hunter cancalibrate the visible laser during the day and wait until night toswitch on a completely different sighting system that is calibrated thesame. In the preferred embodiments of the invention, both lasers areconnected to each other and move as one unit. This coordination is donewith the camera and LCD. With the coordinated system for pin settings,the hunter will have the ability to set five preset ranges for laserassembly and will allow the hunter to adjust for short, medium, and longrange targets. The sighting system works so that the pin settings can beused with the visible sight system, and also such that the pin settingsfor the visible sight is calibrated to the evening sight system.

In accordance with another aspect of the invention, a bow sight isprovided that includes both a visible laser and IR laser assembly, acamera, recorder, a processor, at least one source of light (visible ornight vision oriented) and contains automatically corrects andcompensates for various dynamically changing aiming, shooting, and/orenvironmental conditions. The bow sight can include various integratedsensors or other sensing-type devices, such as a range finder, aninclinometer, and an anemometer, which communicate with a processor orother control device. The processor, based on, e.g., signals from thesensors, may illuminate one or more aim indicators provided within asight array which includes multiple aim indicators. In thisconfiguration, a default sighted-in position can be preliminarilyestablished and designated by a first aim indicator provided within thesight array. Then, during use, the system can correct and compensate forfactors such as distance, shot angle and windage settings. In so doing,effects of environmental and use influences can be mitigated by changinga discrete position of the aim indicator within the sight array basedon, e.g., shooting angle, wind direction, wind velocity, shot distanceor other factors.

In accordance with yet another aspect of the invention, a method ofproviding and using a bow sight. The method includes using a bow sightwherein multiple sight systems are coordinated so that the calibrationof one calibrates all others. The system that is used with the novelmethod can include (i) a base member attachable to a bow, (ii) a sightarray that has multiple electronically selectively tightly spaceddisplayable aim indicators, (iii) an inclinometer, (iv) a range finder,and (v) a processor that cooperates with the inclinometer, range finder,and (vi) a sight system wherein there are at least one visible lasersight that is automatically calibrated with another laser sight, such asan infrared laser sight. The sight system can also include a third videosight. The inclinometer transmits a signal relating to a shooting angleto the processor. The range finder transmits a signal relating to ashooting distance to the processor. Based on such signal(s), theprocessor determines which aim indicator within the sight array shouldbe illuminated, and correspondingly illuminates such aim indicator.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

The components of an embodiment of the system of the present inventionare shown attached to a variety of projectile firing weapons, namely abow, a rifle, and a pistol. The preferred bow sight system hasselectively infrared illuminating capabilities with displayable lasermarks on a LCD screen with a corresponding visible laser spot.

As shown in FIG. 3, a bow system 300 is disclosed in accordance with anembodiment of the current invention. The bow system 300 has a mountingsystem 310 is adaptable for various crossbow, bow, archery, rifle, orfiring arm system. The mounting system can be a conventional mountingsystem 310, well known in the industry. The mounting system 310 is usedto connect the main body 311 of the sight system 320. The sight system320 is composed of a first visible light laser sight, a second infraredlaser sight, and a third video sight that are calibrated with each asdiscussed below. The main body 311 may be mounted to a weapon using avariety of mounting mechanisms, including those disclosed in more detailin U.S. Pat. No. 5,430,967, titled, “Aiming Assistance Device for aWeapon,” issued on Jul. 11, 1995; U.S. Pat. No. 6,574,901, titled,“Auxiliary Device for a Weapon and Attachment Thereof,” issued Jun. 10,2003; and U.S. Pat. No. 6,705,038, titled, “Mounting Assembly for aWeapon,” issued on Mar. 16, 2004, all of which are incorporated hereinby reference in their entirety. Additionally, the sight system mayutilize a mounting mechanism compatible with a mounting rail disclosedin military specifications (e.g., MIL-STD-1913), a “rail grabber”mounting mechanism, levers, screws, bolts, and/or the like.

The main body 311 of the sight system 320 contains an LCD display 321that provides the digital image created by the third video sight, suchas a camera, and aligns properly with calibrated target settings that isestablished by the archer. Embodiments of the present invention involvethe use of the first visible light sight and its automatic calibrationwith the second infrared laser sight. Embodiments of the presentinvention also use a third video sight that can be calibrated with thefirst and second sights. For example, a user can calibrate the firstvisible light sight, which will calibrate the second infrared sight,which can both be calibrated with the video sight so that the video canprecisely shoot at an angle, zoom, and shutter speed, and all othersettings that would allow the calibration of the first sight to save orcalibrate the video settings.

The preferred embodiment employs a conventional diode laser as a sourceof visible laser pointer as a first sight. The system includes zoom inand zoom out buttons 325, on/off switches for both the daylight laserand infrared laser 326, laser adjustment buttons 327, and brightnesssettings 328. The infrared laser pointer assembly and infraredilluminator assembly are used in conjunction.

The visible laser has different settings for different ranges (e.g.,U.S. Pat. No. 5,419,050 A). An adjustable laser beam sight systemcomprises a supporting plate and first, second and third seriallyarranged and rotationally coupled levers mounted on the supporting plateby two pivots. The first pivot rotationally couples the first lever tothe supporting plate and the second pivot rotationally couples the thirdlever to the supporting plate. A first laser sight comprising a laserbeam emitting device is attached to the first lever. Rotation of thethird lever, acting through the second lever, imparts a change indirection of the first lever and the laser beam. A range scale with itsreference center substantially at the second pivot is provided on thesupporting plate. An indicator on the third lever moves across the rangescale as the third lever is moved to adjust the aim of the laser beam,thereby indicating a range setting. Laser archery bow sight (e,g,, U.S.Pat. No. 6,862,813 B1) is another example of such a laser setup. Inaccordance with embodiments of the current invention, a second sight isdesigned so that when the first laser sight is calibrated, the secondsight is automatically calibrated. The second sight can comprise asecond infrared laser beam system wherein when a user calibrates hishunting settings during the day using the first laser sight, the secondsight is automatically calibrated for night-time use.

The use of an LCD screen and a camera can be pivotal with huntingequipment. As shown in FIG. 4, the archer uses a bow 400 with a bowsight 410 in accordance with one embodiment of the current invention.The sight system is used to direct a laser beam path 420 to the target440 using target sight 450. The archer is able to calibrate his firstlaser sight system with conventional known distances prior to theengagement with the animal target 440. For example, the archer iscapable of using conventional pin setting system that will mark offcertain distances. In accordance with embodiments of the currentinvention, the pin setting system will coordinate with the first orsecond sights so that both can be calibrated to the marked offdistances. It should be further noted that in accordance withembodiments of the current invention, a third camera sight system 430and the LCD screen 431 is used so that the target can be additionallyviewed on the LCD screen 431. The third sight system can also be set andcalibrate with the first and second sights. A mark 460 marks thecorresponding spot of target spot 450 that is shown on LCD screen 432.

During the employment of the system at night, there is an optionalsensor that detects the settings for evening settings. Conventionallight sensors can be used to set the system such that the LCD screencoordinates with the camera during the day and switches to the infraredsetting at night. The conventional first visible laser sight 401 isalways calibrated so that any adjustments made to the first visiblelaser sight 401 is coordinated with the second night, or infrared, lasersight 402. The night laser sight 402 works with internal infraredilluminator to illuminate the target with infrared light. The camerasystem can also switch the LCD screen from day time to night timeinfrared screen and allows for the target marking to be on the exacttarget spot 460 as with the conventional laser 401. Although the targetis not visible in the night, the target 460 on the LCD screen is clearlyvisible with the use of the infrared light.

Both the daylight laser sight and evening laser sight are coordinatedand connected so that they move together. In a preferred form of theinvention, the laser is adapted for use with an archery bow. In apreferred form of the invention, the camera and video are alsocoordinated so that when the user calibrates the first or second sights,the camera can also make pre-set adjustments to follow or view thetarget better. There are many ways in which a laser can be adjusted toits target. If the second sight is directly attached, it must beattached in a manner that adjustments made on the first sight is alsomade on the second sight. In an automated system, the calibrationsrequired by the user are stored and extrapolated into the second sightsystem. In other words, a laser may point at a target and a processormay store information regarding its distance and location such that thenight time infrared sight can use it to pinpoint the exact same target.

The laser set may be adjusted using up-down adjuster 610 and 620 inaccordance with another embodiment of the current invention as shown inFIG. 6. The left-right adjuster and a top-bottom adjuster coordinatewith the infrared illuminator assembly so that it functions to capturethe target at night. The divergence of the resulting infraredilluminator beam may be adjusted from a narrow beam to a wide beam byrotation of a beam adjuster. The beam adjustor may have an outsidedimension sized to allow an operator to adjust the beam size. Locatingthe two laser sight assemblies within one beam adjustor can save space.A removable cover camp 551 is used for eyepiece (is eyepiece the rightword this is dust cover for the sighting system) 550.

Conventional day laser 530, the first sight, and night laser 540, thesecond sight, are coupled together as shown in FIG. 5. Because theconventional laser has the ability to adjust vertically and laterally inaccordance with the user's use of dials and pin settings, the couplednight vision laser must match exactly with the settings so that when auser calibrates his first sight during the day, the second sight isautomatically set to the same settings, such as distances, at night.This is done in one embodiment of the invention by physically couplingthe conventional day laser to the infrared night laser and calibratingthem so that each movement with one system is aligned perfectly with theother. In one preferred embodiment, a rotator dial is used that hasnotched pin settings that match the user's use of convention distancesystems, like the pin settings, with precise measurements of the laser.The rotator dial can be set to physically alter the first sight and thesecond sight at the same time so that changing one laser setting changesthe other. And unlike the conventional use of night vision goggles thatwould normally interfere with the shooter, the system in accordance withFIG. 3 stays to the side of the system and does not interfere with thearcher or his resting face on or near the bow of the system 300. To savemoney, the coordination of the first and second sights can be done in avariety of physical ways. They can physically be attached to a differentdial setting as described. They can also be attached in a manner thatthey point precisely only a few inches away from each other so that bothsights follow a parallel pathway to its target.

Many settings can be calibrated and transferred to the second sight.Multiple distances and multiple locations can be spotted and usedinterchangeably between the daytime and nighttime lasers. If a userstores or tracks information regarding the distances of the laser atmany points during the day, the user will be able to access those samedistances with his LCD screen at night. Such a sight system may have apreferred zoom or brightness for the user. Such information may also bestored so that when a user points his second sight at a target, thecamera and LCD screens will immediately allow the user to see the targetand its preferred settings. The use of an LCD has advantages to a nighttime user for bow archers. Because the flew of the string back towardsthe user, the head of an archer is removed from the actual target sightsystem. In a rifle, the scope would be right next to the user's eye, butthat is not the case with an archer. Thus, and LCD that is capable ofzooming in has special advantages for a user that may view the screenfrom a foot to two feet away.

With modern equipment, the multiple sights with the capabilities toilluminate the target at night and the LCD can all be added to a bowwith relative ease. More importantly, the equipment these days are lightand require only minimal adjustments by the user. With time, theseequipment will advance to produce faster and lighter materials, but thecurrent invention ties together the ability for a user to use his sightsystem in multiple settings by allowing the user to calibrate onesetting for one sight and transfer those settings and its usage toanother environment.

In another embodiment of the preferred invention, the calibration of thefirst and second sights to the same target can be done using some formof programmable instructions. This can be done by having the settings ofthe first sight and the second sight be coordinated with a controller.The controller can account for different distance settings and canaccount for the calibration needed so that when a user makes changes tothe first sight, the second sight will calibrate on the same target.

While it is contemplated that the preferred embodiment will employ adiode laser as a source of visible red light, it should be appreciatedthat other types of directed light beams might also be used withoutdeparting from the principles of the invention. For example, it is alsocontemplated that an infrared laser could be used together with gogglesworn by the archer that produce visible light in response to stimulationby infrared light. Similarly, a green or other color visible laser maybe used. And, in some cases, such as nighttime training exercises, anintense incoherent light source might also be used. Accordingly, for thepurpose of the specification, claims, drawings and abstract, “directedbeam” shall mean a beam of energy that is substantially collimated froma source thereof to a target that is within a useful range of an archerybow, and includes without limitation a substantially collimated Gaussianlight beam produced by a laser.

FIG. 5 is an exploded assembly view of the double-laser assemblyconsistent with one embodiment of the invention. The system 500 may beincorporated in a weapon mountable sight wherein the conventional redlaser 530 is coupled to infrared laser system 540. An illuminatorinfrared drive ring 520 and a camera lens 510 also make up the frontview. The location of visible laser pointer assembly and the infraredlaser pointer assembly may be swapped without departing from theinvention.

The visible laser pointer assembly may be a type having a conventionaldiode and spaced a fixed distance from a lens and the infrared laserpointer assembly. The visible laser pointer assembly and the infraredlaser pointer assembly and may be coupled together in conventionalmethods including fusing. The conventional lasers must be calibratedprecisely so that they can coordinate on different targets when the userchanges the setting. In other words, when the user calibrates one laser,the other laser is calibrated exactly the same so that the two laserscan be used together and in conjunction, as well as, one at a timeduring the different parts of the day.

The night sight system includes the ability to see the target in theevening, and it works such that the dot of laser light that is projectedon a distant targeted object can be viewed through the LCD screenwherein the aim indicators that are illuminated or otherwise visually oraudibly displayed at positions which compensate for suchsituation-specific shooting and environmental factors in a manner thatallows an archer to take “dead aim” with, or aim directly at, anintended target at all times. FIG. 7 shows an LCD screen in accordancewith another embodiment of the current invention. LCD system 700 can beused with the evening laser system or can be used with the daytimecamera, used in a conventional camera LCD screen methods well known inthe industry. Spot 740 is calibrated accordingly by both the daylightand evening laser systems. Zoom features 730 and 731 and brightnesssetting 720 and on/off button 721 are conventional buttons on LCD camerascreen systems.

FIG. 8 shows a system where the first sight and the second sight areattached to each and coordinated so that the calibrations made by thefirst sight transfer to the calibrations of the second sight. Thecustomer using the dial in 840 can move the laser vertically either upor down to move lasers 820 and 810 to each of the distance settings inpins 841, 842, 843, 844 and 845. Each pin 841-845 can be adjustedvertically either up or down to set the distance for the lasers 820 and810. The hunter matches (830) with is his current sight pins (240) inthe daylight visible hours to enable the hunter to The eyepiece(eyepiece)820 works in conjunction with various pin settings 841-845that has different settings for various distances calibrated by theuser. The daytime laser 820 is connected with the evening laser system810 with a connector 821 such that any coordinated movement to adjustthe calibration on the target is done together and coordinated so thatany setting set by the daytime laser system can be used by the eveninglaser system. Optionally, a third sight, that includes a camera and LCDscreen, can be coordinated with the first daytime laser sight and thesecond evening laser sight.

The following is a possible manner to use the current invention. Anarcher uses the current bow sight by mounting it on his/her bow. Duringthe day, the archer finds a location to hunt and calibrates hisconventional pin settings (240) so that the archer knows which pinsetting to use for various distances. The archer calibrates his firstsight (841), which includes a conventional red laser, so that thedifferent distances match with the settings. The archer can optionallyhave a rangefinder in the system that can measure exact distances. Thearcher is now prepared to point, direct the laser, and have an immediateassessment of how to fire depending on the pin setting of the bow. Thecalibration of the first sight automatically calibrates the second sightsystem. The automatic calibration is done using a manual connectionbetween the first and the second sight, however, the calibration of thesecond can be done using a program if both sights are in sync with aprocessor, or controller, than can account for the different settingsand the different distances. This can be done using conventionalprocessors or controller, and optionally, it can be done using a mobilesmart device, such as a mobile phone that can attach to the system. Inthis embodiment, the mobile smart device can also act as the LCD screenand camera that is part of the third sight system. The archer will thenperform the same distance setting process with pins 842-845 to set theother distances for the pins with the traditional sighting system (240).

In another embodiment, the multiple sights can only be manually adjustedand individually adjusted when there is switch that goes from“calibration” to “non-calibration.” Only in the “non-calibration” modecan each of the sights be calibrated to different targets or todifferent distances. In this embodiment, each of the sights will requireits own adjustment capabilities. But in this embodiment, there must be a“calibration” mode where a user can either switch a button or turn onthe feature of a program that makes the first sight and second sightscalibrate together. For purposes of this invention, the discussionfocusses on only when the first and second sights are linked so that thecalibration of the first sight calibrates the second sight.

Once the archer coordinates and calibrates the distances of the firstsight, the second sight should also be calibrated. The archer can waitfor quite some time before any game shows up. The switch from day tonight can bring out different hunt, and in the current system, thesecond sight system can be used in the different environmentalconditions. The different environmental conditions may be a change inweather, temperature, but mostly, it is contemplated that the differentchange in environmental conditions is a change in time, from day tonight. The second sight uses a different laser, an infrared laser, andwith its use of an infrared showing LCD screen. The LCD can act as athird sight that stores information and is calibrated so that settings,such as particular zooms, are memorized and calibrated when the userdecides to target.

There are pin settings, and the calibration of the pin settings caninclude at least five preset ranges for various distances to the targetusing an eye piece that matches five pin settings to various distances.Other settings that may include for the third sight, brightness, zoom,shutter speed, zoom of the LCD screen. It may include all theconventional settings of a normal camera, which can be coordinated withthe calibrations of the first or second sight.

Various embodiments of a bow sight will now be described that achievethese and many other goals, it being understood that otherconfigurations may be provided that fall within the scope of the presentinvention.
